Face Masks May Have Helped Japan Battle Virus

The Four Percent

When the coronavirus arrived in Japan, people did what they normally do: They put on masks.

Face coverings are nothing new there. During flu and hay fever seasons, trains are crowded with commuters half-hidden behind white surgical masks. Employees with colds, worried about the stigma of missing work, throw one on and soldier into the office.

Japan has reported more than 17,000 infections and just over 900 deaths, while the United States, with a population roughly two and a half times as large, has topped 1.9 million cases and is approaching 110,000 deaths.

“Japan, I think a lot of people agree, kind of did everything wrong, with poor social distancing, karaoke bars still open and public transit packed near the zone where the worst outbreaks were happening,” Jeremy Howard, a researcher at the University of San Francisco who has studied the use of masks, said of the country’s early response. “But the one thing that Japan did right was masks.”

During the pandemic, scientists have found a correlation between high levels of mask-wearing — whether as a matter of culture or policy — and success in containing the virus.

“I think there is definitely evidence coming out of Covid that Japan, as well as other countries which practice mask-wearing, tend to do much better in flattening the curve,” said Akiko Iwasaki, a professor of immunobiology at Yale.

With states beginning to allow varying degrees of economic reopening, large protests against police brutality being held in dozens of cities and warmer weather inviting people outside, forecasters tracking the Covid-19 pandemic in the United States are approaching a difficult juncture.

Prince William counts as one among thousands of British volunteers assisting on a crisis help line during the coronavirus lockdown, Kensington Palace announced in a message marking the end of Volunteers’ Week.

“I’m going to share a little secret with you guys, but I’m actually on the platform volunteering,” Prince William, the Duke of Cambridge, said during a video call in which he and his wife, Catherine Middleton, the Duchess of Cambridge, thanked volunteers for their work.

From London to Sydney, crowds of people around the world defied public health warnings and turned out in solidarity with U.S. protesters calling for justice in the death of an African-American man, George Floyd, killed in policy custody in Minneapolis. Health experts have warned that the demonstrations could accelerate the spread of the coronavirus, especially among people not wearing masks.

In Australia, huge crowds turned out in Sydney, Melbourne and many other communities in support of the Black Lives Matter movement calling for an end to systemic racism and Aboriginal deaths in police custody.

The health minister in Britain urged residents not to gather for demonstrations in London, Manchester and Birmingham. But large crowds appeared — despite the cold weather, the rain and warnings by the police that mass gatherings would violate the rule that only six people from different households could gather outside during the pandemic.

Police in Northern Ireland announced on Saturday that organizers of “Black Lives Matter” protests in Belfast and Derry will be reported to the Public Prosecution Service for breaking coronavirus restrictions.

“We estimate there were less than 500 people in attendance at each event and a significant number of Community Resolution Notices (CRNS) and fines were issued,” said Assistant Chief Constable Alan Todd, who added that “Health Protection Regulations are in place to protect us all during this pandemic and it is everyone’s responsibility to adhere to them to protect our society.”

In Paris, on a day the Palace of Versailles reopened to visitors and tourists, the authorities barred people from gathering in front of the United States Embassy, but thousands protested there anyway in the late afternoon, as well as near the Eiffel Tower, echoing a protest earlier this week that drew nearly 20,000 people in memory of Adama Traoré, a Frenchman who died in police custody in 2016. On Friday, police officially banned protests on the Champ-de-Mars for June 6, citing coronavirus concerns.

The weekend ahead of New York City’s start of gradual reopening, Gov. Andrew M. Cuomo reported 35 new coronavirus deaths statewide, a drop of seven from the day before and the lowest daily total in the last two months.

“This is really, really good news compared to where we were,” Mr. Cuomo said Saturday during his daily briefing in Albany. “This is a big sigh of relief.”

Under Phase 1 of reopening, set to begin Monday, retail stores will be allowed to open for curbside or in-store pickup, and nonessential construction and manufacturing can resume, returning as many as 400,000 people to the work force.

For the first time in three months there is a scent of economic optimism in the air. Employers added millions of jobs to their payrolls in May, and the jobless rate fell, a big surprise to forecasters who expected further losses. Businesses are reopening, and the rate of coronavirus deaths has edged down. The Trump administration has begun pointing to what are likely to be impressive growth numbers as the economy starts to pull out of its deep hole.

All of that is good news. But there are clear signs that the collapse of economic activity has set in motion problems that will play out over many months, or maybe many years. If not contained, they could cause human misery on a mass scale and create lasting scars for families.

The fabric of the economy has been ripped, with damage done to millions of interconnections — between workers and employers, companies and their suppliers, borrowers and lenders. Both the historical evidence from severe economic crises and the data available today point to enormous delayed effects.

    • How many people have lost their jobs due to coronavirus in the U.S.?

      The unemployment rate fell to 13.3 percent in May, the Labor Department said on June 5, an unexpected improvement in the nation’s job market as hiring rebounded faster than economists expected. Economists had forecast the unemployment rate to increase to as much as 20 percent, after it hit 14.7 percent in April, which was the highest since the government began keeping official statistics after World War II. But the unemployment rate dipped instead, with employers adding 2.5 million jobs, after more than 20 million jobs were lost in April.

    • Will protests set off a second viral wave of coronavirus?

      Mass protests against police brutality that have brought thousands of people onto the streets in cities across America are raising the specter of new coronavirus outbreaks, prompting political leaders, physicians and public health experts to warn that the crowds could cause a surge in cases. While many political leaders affirmed the right of protesters to express themselves, they urged the demonstrators to wear face masks and maintain social distancing, both to protect themselves and to prevent further community spread of the virus. Some infectious disease experts were reassured by the fact that the protests were held outdoors, saying the open air settings could mitigate the risk of transmission.

    • How do we start exercising again without hurting ourselves after months of lockdown?

      Exercise researchers and physicians have some blunt advice for those of us aiming to return to regular exercise now: Start slowly and then rev up your workouts, also slowly. American adults tended to be about 12 percent less active after the stay-at-home mandates began in March than they were in January. But there are steps you can take to ease your way back into regular exercise safely. First, “start at no more than 50 percent of the exercise you were doing before Covid,” says Dr. Monica Rho, the chief of musculoskeletal medicine at the Shirley Ryan AbilityLab in Chicago. Thread in some preparatory squats, too, she advises. “When you haven’t been exercising, you lose muscle mass.” Expect some muscle twinges after these preliminary, post-lockdown sessions, especially a day or two later. But sudden or increasing pain during exercise is a clarion call to stop and return home.

    • My state is reopening. Is it safe to go out?

      States are reopening bit by bit. This means that more public spaces are available for use and more and more businesses are being allowed to open again. The federal government is largely leaving the decision up to states, and some state leaders are leaving the decision up to local authorities. Even if you aren’t being told to stay at home, it’s still a good idea to limit trips outside and your interaction with other people.

    • What’s the risk of catching coronavirus from a surface?

      Touching contaminated objects and then infecting ourselves with the germs is not typically how the virus spreads. But it can happen. A number of studies of flu, rhinovirus, coronavirus and other microbes have shown that respiratory illnesses, including the new coronavirus, can spread by touching contaminated surfaces, particularly in places like day care centers, offices and hospitals. But a long chain of events has to happen for the disease to spread that way. The best way to protect yourself from coronavirus — whether it’s surface transmission or close human contact — is still social distancing, washing your hands, not touching your face and wearing masks.

    • What are the symptoms of coronavirus?

      Common symptoms include fever, a dry cough, fatigue and difficulty breathing or shortness of breath. Some of these symptoms overlap with those of the flu, making detection difficult, but runny noses and stuffy sinuses are less common. The C.D.C. has also added chills, muscle pain, sore throat, headache and a new loss of the sense of taste or smell as symptoms to look out for. Most people fall ill five to seven days after exposure, but symptoms may appear in as few as two days or as many as 14 days.

    • How can I protect myself while flying?

      If air travel is unavoidable, there are some steps you can take to protect yourself. Most important: Wash your hands often, and stop touching your face. If possible, choose a window seat. A study from Emory University found that during flu season, the safest place to sit on a plane is by a window, as people sitting in window seats had less contact with potentially sick people. Disinfect hard surfaces. When you get to your seat and your hands are clean, use disinfecting wipes to clean the hard surfaces at your seat like the head and arm rest, the seatbelt buckle, the remote, screen, seat back pocket and the tray table. If the seat is hard and nonporous or leather or pleather, you can wipe that down, too. (Using wipes on upholstered seats could lead to a wet seat and spreading of germs rather than killing them.)

    • Should I wear a mask?

      The C.D.C. has recommended that all Americans wear cloth masks if they go out in public. This is a shift in federal guidance reflecting new concerns that the coronavirus is being spread by infected people who have no symptoms. Until now, the C.D.C., like the W.H.O., has advised that ordinary people don’t need to wear masks unless they are sick and coughing. Part of the reason was to preserve medical-grade masks for health care workers who desperately need them at a time when they are in continuously short supply. Masks don’t replace hand washing and social distancing.

    • What should I do if I feel sick?

      If you’ve been exposed to the coronavirus or think you have, and have a fever or symptoms like a cough or difficulty breathing, call a doctor. They should give you advice on whether you should be tested, how to get tested, and how to seek medical treatment without potentially infecting or exposing others.


While the government can’t wave a wand and bring back industries that are semi-permanently shuttered, it can act — and has acted — to try to keep demand for goods and services at pre-crisis levels. That, in turn, can smooth the path for other sectors to grow so that there is not a prolonged depression of jobs, income and investment, with a resulting reduction in the economy’s long-term potential.

But whether the infection can cause birth defects, miscarriage, premature birth or stillbirth is not yet known. Newborns have become infected, but it’s not clear whether they contracted the virus before, during or after birth, or if breastfeeding can transmit the virus.

Even so, the report says that for women who are wondering whether this is a safe time to conceive, “based on limited data, there does not seem to be a compelling reason to recommend delaying pregnancy.”

For years, Gildo Negri visited schools to share his stories about blowing up bridges and cutting electrical wires to sabotage Nazis and fascists during World War II. In January, the 89-year-old made another visit, leaving his nursing home outside Milan to help students plant trees in honor of Italians deported to concentration camps.

But at the end of February, as Europe’s first outbreak of the coronavirus spread through Mr. Negri’s nursing home, it fatally infected him, too.

The virus, which is so lethal to the old, has hastened the departure of these last witnesses and forced the cancellation of commemorations. It has also created an opportunity for rising political forces who seek to recast the history of the last century in order to play a greater role in remaking the present one.

Throughout Europe, radical right-wing parties with histories of Holocaust denial, Mussolini infatuation and fascist motifs have gained traction in recent years.

Those conditions increase infection risks, and not only for their frail older clients. Almost a third of home care workers, a heavily female work force, are themselves over 55, and most are black or Hispanic, groups that have proved particularly vulnerable to Covid-19.

Personal protective equipment, or P.P.E., has proved hard to acquire, however. With hospitals and nursing homes scrambling for supplies, “this was the forgotten sector,” said Dr. Nathan Stall, a geriatrician at the University of Toronto.

“Home care workers are probably unknowingly involved in the transmission of Covid-19, especially when they’re not equipped with sufficient P.P.E.,” he added.

When the country was under lockdown, at least the rules were mostly clear. Essential workers ventured out; everyone else sheltered in.

Now states are lifting restrictions, but detailed guidance about navigating the minutiae of everyday life is still hard to come by — and anyway, there’s never going to be a ready solution to every problematic circumstance you may encounter.

But young healthy adults and children should also consider the protection of people around them, including family members, colleagues or friends who are vulnerable, said Dr. Barbara Taylor, an infectious disease specialist at The University of Texas Health Science Center at San Antonio.
